Child containment device and retention device assembly

ABSTRACT

A retention device is assembled to a child containment device and is rotatable about each side of the retention device. In particular, the retention device (e.g., a tray or toy bar) includes a first engagement portion adjacent a first end of the retention device and a second engagement portion adjacent a second end of the retention device. The child containment device includes a seat portion, a first frame member adjacent a first side of the seat portion, and a second frame member adjacent a second side of the seat portion. Mating engagement portions are disposed on each frame member and engage the engagement portions of the retention device. To rotate the retention device relative to the child containment device, one of the engagement portions is disengaged from the respective mating engagement portion, and the retention device is rotated relative the other engagement portion.

BACKGROUND OF THE INVENTION

Many child containment products, such as swings, strollers, high chairs,and bouncer seats, have retention devices, such as trays or toy bars,that are disposed in adjacent to the portion of the child containmentproduct that supports the child (e.g., a seat). In addition, theretention device in many child containment products serves as arestraint device, helping to retain the child in the seat so the childdoes not fall out and sustain injuries. The retention devices,therefore, are typically installed in such a fashion that the childcannot be removed from, or placed into, the seat of the childcontainment device without removing the retention device or somehowmoving the tray or toy bar away from the seat.

Most existing products allow for the retention device to simply unsnapfrom both sides and completely disengage from the supporting structure.A problem with these existing products is that it can be difficult todisengage the sides of the retention device while holding a child.

Thus, there is a need in the art for an improved method of assembling aretention device (e.g., trays, toy bars) to a child containment device.

As noted above, FIG. 1 illustrates a tray retention device 100 accordingto one embodiment of the invention. The tray 100 includes an elongatedbody 101, an upper surface 102, a lower surface 104 (shown in FIG. 5), afirst end 106, a second end 108, a front edge 110, and a rear edge 112(shown in FIG. 5). The upper surface 102 is spaced apart and oppositefrom the lower surface 104, and the upper surface 102 is configured forholding items, such as food, drinks, or toys, that a child or caregivermay want to put on the tray. The first end 106 is spaced apart andopposite from the second end 108, and the upper 102 and lower surfaces104 extend between the first end 106 and the second end 108. Similarly,the front edge 110 and back edge 112 are opposite and spaced apart fromeach other, and each edge 110, 112 extends between the ends 106, 108 andthe upper 102 and lower surfaces 104.

According to various embodiments, as shown in FIGS. 1 through 7, a firstengagement portion 114 is disposed adjacent the first end 106, and asecond engagement portion 116 is disposed adjacent the second end 108.FIGS. 2 through 7 illustrate embodiments of the engagement portions 114,116 in which the engagement portions 114, 116 are substantially C-shapedclips. In particular, each C-shaped clip 114, 116 has two edges 122, 123and a flange 124 that extends radially outwardly from the outer edge122.

In addition, according to the embodiment shown in FIGS. 2 and 3, anattachment portion 125 extends radially outwardly from a portion of eachC-shaped clip 114, 116 disposed between the edges 122, 123. Theattachment portion 125 of the first C-shaped clip 114 is secured to thelower surface 104 of the tray 100 adjacent the first end 106, and theattachment portion 125 of the second C-shaped clip 116 is secured to thelower surface 104 adjacent the second end 108. In this particularembodiment, each clip 114, 116 and its attachment portion 125 isseparately formed from the tray 100. To secure the attachment portion125 to the tray 100, a fastener (e.g., a screw, a bolt, or othersuitable fastener) is engaged in each of one or more openings 127extending through the attachment portion. However, in other embodiments(not shown), the attachment portion may be secured to the tray 100 by asnap fit, tongue and groove fit, adhesive, or other suitable means. Inother alternative embodiments, such as the embodiment shown in FIGS. 5through 7, the attachment portion 425 is integrally formed with the tray100.

Furthermore, in the embodiment shown FIGS. 1 through 3, each C-shapedclip 114, 116 defines an elongated slot 128 that extends through thesurface of the clip 114, 116. The opening defined by the slot 128 isoriented to be substantially perpendicular to the longitudinal axis X ofthe clips 114, 116 and the boundaries of the slot 128 are within theperimeter of the clip 114, 116. However, in other embodiments, such asthe embodiment shown in FIGS. 4 through 7, the clips 114, 116 do notinclude slots 128.

The C-shaped clips 114, 116 according to the embodiment shown in FIGS. 1through 7 are molded from a resilient material, such as plastic (e.g.,polyolefin, ABS, or other suitable plastic material), thin sheet metal(e.g., stamped or rolled), or combination thereof, and the edges 122,123 are biased substantially toward each other. To urge edge 122 in aradially outward direction away from edge 123, a user pulls the flange124 extending from the edge 122 away from the edge 123 and/or pulls theflange 124 toward the upper surface 102 of the tray 100, which moves theedge 122 in a radially outward direction from the edge 123.

In the embodiments shown in FIGS. 1 through 7, the tray 100 includes ahorn 135 that extends downwardly from the lower surface 104 of the tray100 and is disposed adjacent the front surface 110 of the tray 100. Whenthe tray 100 is secured to the swing 200, a distal end of the horn 135is adjacent a seat portion 202 of the swing 200 to prevent a childseated therein from slipping out of the seat portion 202 underneath thetray 100. In various other embodiments (not shown), the horn may be partof the seat portion of the swing, extending upwardly therefrom such thatthe distal end of the horn is adjacent the lower surface of the tray andis thus not part of the tray 100.

In the embodiments described above and shown in FIGS. 1 through 7, theupper 102 and lower surfaces 104 of the tray 100 have a substantiallyrectangular shape. However, in other various embodiments, the upper andlower surfaces of the tray may be substantially triangular,substantially elliptical, substantially trapezoidal, substantiallycircular, or other suitable polygonal shape.

In addition, the engagement portions according to the embodimentsdescribed above and shown in FIGS. 1 through 7 are substantiallyC-shaped clips. However, in various other embodiments, the engagementportions may be detachable collars that define a substantiallycylindrically shaped inner surface. For example, in a particularalternative embodiment (not shown), the detachable collars may includeat least two arcuate shaped portions that are hingedly connected along afirst edge of each portion. The second edges of each portion, which areopposite and spaced apart from the first edges, are biased toward eachother by a spring that is disposed adjacent the first edges.

Furthermore, in the embodiments described above and shown in FIGS. 1through 7, the retention device is a tray. However, in other variousembodiments, the retention device may be any suitable device that isattachable to a child containment device, including, but not limited to,a toy bar, a retention bar, or one or more bars on which other devices(e.g., a tray, a car seat, or an accessories holder) may be mounted.

Child Containment Device

FIG. 1 illustrates an embodiment of a swing child containment device200. The swing 200 includes a seat portion 202 in which a child isdisposed and supported above a support surface and frame members 204,206 adjacent each of two opposite and spaced apart sides of the seatportion 202. A first mating engagement portion 208 is disposed adjacentthe first frame member 204, and a second mating engagement portion 209is disposed adjacent the second frame member 206.

In the embodiments shown in FIGS. 1 through 7, each frame member 204,206 has a substantially cylindrical shape, and the first and secondmating engagement portions 208, 209 each include a sleeve that has asubstantially cylindrical outer surface 229 and is disposed around atleast a portion of each frame member 204, 206. Each sleeve 208, 209includes circumferential walls 210 adjacent the ends of each sleeve 208,209, and each wall 210 extends radially outwardly from the outer surface229 of the sleeve 208, 209. In the embodiment shown in FIGS. 2 and 3, atab 214 is disposed between the walls 210 of each sleeve 208, 209 andextends radially outwardly from the outer surface 229 of the sleeve 208,209.

In the embodiment shown in FIGS. 1 through 7, the sleeves 208, 209 areseparately formed from the frame members 202, 204 and are disposedthereon. In one embodiment, the sleeves 208, 209 are riveted to theframe members 202, 204. In addition, in certain embodiments, the sleeves208, 209 are formed of a plastic material (e.g., ABS, polypropylene,nylon, or other suitable plastic material), a metallic material, orcombination thereof. In a particular embodiment, the sleeves 208, 209are formed by injection molding.

As discussed above, in the embodiments shown in FIGS. 1 through 7, theframe members 204, 206 have a substantially cylindrical shape. However,in other alternative embodiments (not shown), each frame member may havean elongated, non-cylindrical shape, such as substantially elliptical,substantially triangular, substantially rectangular, or other suitablepolygonal shape. In some of these alternative embodiments, an innersurface of the sleeve that is disposed around a portion of the framemember has a shape that is substantially similar to the shape of theframe member such that the sleeve does not rotate relative to the framemember.

In addition, in the embodiments described above in relation to FIGS. 1through 7, the sleeves 208, 209 are separately formed from the framemembers 204, 206 and are disposed thereon. However, in various otherembodiments, the sleeves may be integrally formed on the frame memberssuch that each frame member defines two substantially circumferentialwalls that are axially spaced apart from each other along a longitudinalaxis of the frame member. In a particular embodiment, a tab extends in aradially outward direction from the frame member and is disposed betweenthe substantially circumferential walls.

Furthermore, in the embodiments shown in FIG. 1 through 7, thecircumferential walls 210 are shown to be solid, having no breaks inthem. However, in other various embodiments (not shown), thecircumferential walls may include two or more sections that are spacedapart along the circumference of the sleeve (or the frame member).

Furthermore, in the embodiments described above and shown in FIGS. 1through 7, the child containment device is a swing, and reference ismade to a seat portion 202 of the swing 200 in which a child may beplaced and supported above a support surface. Because the childcontainment device could include any suitable device for supporting achild above a support surface, including, but not limited to, astroller, a high chair, a bouncer seat, an infant carrier, a boosterseat, a bassinet, a play yard, or a co-sleeper, the term “seat portion”should include any portion of the child containment device in which achild may be disposed and supported above a support surface, not justportions in which a child can be disposed in a seated, or substantiallyupright position.

Methods of Assembly and Use

FIGS. 1 through 4 illustrate embodiments in which the tray 100 issecured to the swing 200 by engaging the first engagement portion 114with the first mating engagement portion 208 and the second engagementportion 116 with the second mating engagement portion 209. To secure thetray 100 to the swing 200, the user urges the flange 124 of eachC-shaped clip 114, 116 (one at a time or simultaneously) in a directionaway from the edge 123 (e.g., radially outwardly from the edge 123and/or toward the upper surface 102) to expand the width of the openingbetween the edges 122, 123 of the clip 114, 116, which allows the outersurface 229 of each sleeve 208, 209 to be engaged adjacent the innersurface 129 of each clip 114, 116, respectively. The user then releasesthe flange 124 of each clip 114, 116, and the inner surface 129 of eachclip 114, 116 is biased against the outer surface 229 of each sleeve208, 209. Each clip 114, 116 is disposed around each sleeve 208, 209,respectively, such that side edges 131, 132 of each clip 114, 116 aredisposed between the circumferential walls 210 of each sleeve 208, 209,respectively. Furthermore, in the embodiment shown in FIGS. 2 and 3, thetab 214 of each sleeve 208, 209 is disposed within the slot 128 of eachclip 114, 116, respectively. In such an embodiment, the tab 214 has alength and a width that is less than a corresponding length and width ofthe slot 128 such that the tab 214 fits within the slot 128.

The tray 100 may be completely removed from the swing 200 or rotatedabout each frame member 204, 206. For example, as shown in FIG. 5, thetray 100 may be rotated to the right of the seat portion 202 about thesecond frame member 206 by disengaging the first clip 114 from the firstsleeve 208. In particular, the flange 124 of the first clip 114 is urgedaway from the edge 123, and the first end 106 of the tray 100 is urgedaway from the first frame member 204 such that the inner surface 129 ofthe clip 114 disengages the outer surface 229 of the sleeve 208. Whilethe first end 106 of the tray 100 is being urged away from the firstframe member 204, the second clip 116 rotates about the second sleeve209. The second clip 116 is prevented from moving axially along thesecond frame member 206 by the circumferential walls 210 of the secondsleeve 209.

In the embodiment shown in FIGS. 2 and 3 in which the clips 114, 116include the slot 128 and the sleeves 208, 209 include in the tab 214,the slot 128 of the first clip 114 also disengages the tab 214 by beingmoved radially outwardly from the tab 214 with the urging of the flange124 away from the edge 123 of the clip 114. In addition, the tab 214 ofthe second sleeve 209 moves through the slot 128 of the second clip 116to guide the motion of the tray 100 about the longitudinal axis Xextending through the second frame member 206. According to oneembodiment, the length of the slot 128 defines the limits of the rangeof motion the tray 100 can travel about the particular axis of rotationby the distance the tab 214 can travel along the length of the slot 128.

Referring back to the embodiments described in FIGS. 1 through 7, torotate the tray to the left of the seat portion 202 about the firstframe member 204, the second clip 116 is disengaged from the secondsleeve 209, and the tray 100 is rotated about the longitudinal axis Xextending through the first frame member 204. FIG. 6 illustrates oneembodiment in which the tray 100 is rotated to the left of the seatportion 202 of the swing 200. In addition, to completely disengage thetray 100 from the swing 200, both clips 114, 116 are disengaged from thesleeves 208, 209, respectively, one at a time or simultaneously, and thetray 100 is moved away from the swing 200.

In the embodiment described above in relation to FIGS. 2 and 3, eachclip 114, 116 defines slot 128 that receives tab 214 that extendsradially outwardly from each sleeve 208, 209, respectively. However, invarious alternative embodiments, such as shown in FIG. 8, a protrusionor tab 318 extends radially inwardly from an inner surface 329 of eachclip 314, 316, and a slot 428 is defined on an outer surface 429 of eachsleeve 408, 409. When the clips 314, 316 are engaged with the sleeves408, 409, the tab 318 on each clip 314, 316 is engaged into the slot 428defined in each sleeve 408, 409, respectively.

In the embodiments described above and shown in FIGS. 1 through 8, thetray is rotatable about the first or second frame member of the swingthrough a plane that is substantially perpendicular to the supportsurface (i.e., about an axis that is substantially parallel to thesupport surface). However, in other various embodiments (not shown), thetray or other type of retention device may be rotated through a planethat is at an angle less than 90° to the support surface. For example,in various embodiments, the retention device may be attached tovertically or diagonally oriented frame members of a child containmentdevice, and, accordingly, the retention device would be rotatablerelative to the frame members through a plane that is substantiallyparallel or at an angle of between 0° and about 90° relative to thesupport surface.
